The film, adapted from the non-fiction New York Times bestseller of the same name, revolves around five interconnected couples dealing with pregnancy and adoption.

Cameron Diaz spent months on set wearing stuffed bras and prosthetic pregnancy bellies to mimic the various stages of her character Jules' pregnancy in the film. She said she was in fake labour for many hours, filming the birth scene.

"We wanted to create in that scene, it's that moment where everything becomes real where the baby is there, it's with you, It's a big moment for the characters."

Singer Cheryl Cole got a loud reception on the red carpet from fans and Diaz was complimentary about the 28 year-old's first acting part.

"I think she's pretty savvy when it comes to being on a set and knowing how to handle herself. She played it beautifully. She was fun and entertaining and for us, she provided a great energy for the set."

The film also stars Jennifer Lopez, Elizabeth Banks, Dennis Quaid and Brooklyn Decker.
